Unification of ?-Minkowski and extended Snyder spaces
نویسندگان
چکیده
In a recent paper, we have studied associative realizations of the noncommutative extended Snyder model, obtained by including Lorentz generators (tensorial coordinates) and their conjugated momenta. this extend result to also incorporate covariant realization $\kappa$-Poincar\'e spacetime. We obtain coproduct, star product twist in Weyl-ordered realization, first order noncommutativity parameters. This could help construction quantum field theory based on geometry.

some properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...

In this paper, by the Gauss equation of the induced Chern connection for Finsler submanifolds, we prove that if M is an umbilical hypersurface of a Minkowski space (V , F ), then either M is a Riemannian space form or a locally Minkowski space. AMS subject classifications: 53C60, 53C40

متن کاملExtended Graph Unification
We propose an apparently minor extension to Kay's (1985} notation for describing directed acyclic graphs (DAGs}. The proposed notation permits concise descriptions of phenomena which would otherwise be difficult to describe, without incurring significant extra computational overheads in the process of unification. We illustrate the notation with examples from a categorial description of a fragm...
متن کاملHoroballs in simplices and Minkowski spaces
Our interest in horoballs comes on the one hand from the problem of describing the dynamics of certain important classes of self-maps of convex cones, and on the other hand from the work of Rieffel [17] on quantum metric spaces in the context of Connes’ noncommutative geometry. Horofunctions also appeared recently in a general law of large numbers for random walks on groups [11]. As is remarked...
